The host name earlier was servername.abc.net , but now it should be only servername .
When I go to the web based OEM or DB Control in Oracle 10g, it shows the OEM screen. On the same screen I see the error
java.lang.Exception: UnknownHostException sending request :: servername.abc.net
I want the host name to be servername not servername.abc.net
Which oracle file needs to be changed..?
